American Standard Advice

bgbamaOctober 24, 2012

I am looking at two different systems for my home.

Approximately 2800 sqft 2-story home.

I current have a 2 ton and 4 ton unit that are about 20 years old.

I live in Houston with very hot and humid summers.

I am looking at the American Standard Gold Xi 15 series air conditioners for both units with a Platinum SV variable speed communicating furnace. My installer recommends upgrading to the Platinum XM allegiance 16 unuts due to the 2 stage cooling. The ugrade would cost an additional $900.

What does everyone think of the two stage cooling units, given my climate, and would the upgrade be worth it.

Thank you.

Both the 15 and 16 are good units. 2-stage provides some comfort benefits by achieving longer runtimes in low stage. Is the $900 upcharge for both units? If so, that is reasonable and I would recommend the upgrade.

One caveat: I believe you can use a single-stage outdoor unit with the communicating furnace and communicating control, but with a 2-stage NON-COMMUNICATING outdoor unit (the Allegiance 16), you would need to use a standard thermostat (like the ACONT803). So if you want 2-stage and a fully communicating system, better to consider the Allegiance 20.
